-n 'o att wwm may @encerrar e it known that l', ALEXANDER et firmenie, a, citizen of tbe United @tetese end resident of Cliimegoe illinois, lieve invented certain new end ueeinl Improvements in Shingle-Getting Machines for Composition Booting, of which the :following is al specification.

This invention relates to cutting; strips of shingles frein e, roll of composition roofing. Machines .beve been devised ior cerrying out this operation but their operetion has not been sniliciently speedy for the enormous production requiredl The roofing; materiel must be cut While het end heretofore the knives would gum 'up so that poor looking article resultedo Again, it iles been diilicult to nelre the notches between the shingles zibsolutelgT the correct size beceuse die roofing would slip between tbe iced rollersi The object oit this invention is to devise e nieebine tbet Will overcome all these obstecles sind it consiste essentially in e tWobleded rotery ltnile 'Whose bledes ere diiierent in idtli end in sliepe.

Tile invention bes been illustrated in the accompanying drawing, in whicha Figure ll ie diegreinlnstio side eleve-l tion ei. the ineebinc.

Fig. f2; is e pien View of tbe machine, sind Fig. 3 shows e Inodiiied forni of cutting knife. y

ln the drawings, the numeral il represents e, roll of composition rooting l2, adept ed to be 'lied by ineens of rollers 13 and i4; over e trible i5, equipped With lingers 16, projecting' from its cutting; edge. The cutting lrnife'is carried by e, shaft 17, suitably knife is the fell Width of the reeling i2 to be cut end is composed of narrower blade 18, eerriei'fl disinetricelly opposite Vanother blade 19?. "si-'bieb bes recesses 90 in its cutting edge edejeted to register with the iingers or prof jections lfi ci tlie table 15. in the modified term oi? knife shown in lliigu 3 the narrow blade 2l is similar te i8 end tbe Wider blade 22 similer to i9, except that tbe blades 2l end ere et en engle to eecb other, instead of in tbe seme pleine es in Fig. l.,

roll ll by the rollers i3 end ltover the table l5 into the position shown in Fig-.gu i when the blede 19 rotates and by cleavage eetion cuts out a strip of shingles outlined by the lines 20 and 23 to 26 extending treneversel?)T of tbe rooting 12. The strip felle from the trible from whence it is conveyed away. Re inoval of this strip leeres fingere l@ pre`- jeeting from, the roofing materiel but es the materiel is continually ifed forward, by tbe time the knife has rotated enough to bring the narrow blade 18 around to cutting position, tbe roofing bes edvenced just title length oi the fingers l@ and tbis'blede cute tlieni oit', leaving e straight edge l25 for the next shingle strip. Tbie operation is then repeated indefinitelyn lt it ie desired to very tbe length oi tbe body of the shingle strip5 tlien the blades must be placed et en angle to cimeli other, es s ion'n in liig. 3, to permit more rooting ine,- teriil to be fed over the table le betere the Wide blade makes its cut.

.als the blade which cuts tbe notches be tween tbe shingles chops tbe Waste elettr oi tbe opening there is no clienee for tile gemining up experienced in previous nieeliines. lit is te be understood theft tlie terms ci? tbe inventieri disclosed ere illustrative only end should not be considered es limiting tbe scene oi tbe invention.
